If the average marks of 100 students is 50, what will be the total marks
5000
Calculating Total Marks from Average and Number of Students
To find the total marks for a group of students, we use the relationship between average, total, and the number of items (in this case, students). The average is calculated by dividing the total sum by the number of items.
Understanding the Relationship
The basic formula for calculating the average is:
\text{Average} = \frac{\text{Total}}{\text{Number}}
In this question, we are given the average marks and the number of students, and we need to find the total marks. We can rearrange the formula to solve for the total:
\text{Total} = \text{Average} \times \text{Number}
Applying the Formula to Find Total Marks
We are given the following information:
- Average marks of the students = 50
- Number of students = 100
Using the rearranged formula, we can calculate the total marks:
\text{Total marks} = \text{Average marks} \times \text{Number of students}
\text{Total marks} = 50 \times 100
\text{Total marks} = 5000
Therefore, the total marks obtained by the 100 students is 5000. This simple calculation helps us determine the overall score when we know the average performance and the size of the group.
Summary of Calculation for Total Marks
Here's a quick look at the values and the result:
| Value | Amount |
|---|---|
| Average marks | 50 |
| Number of students | 100 |
| Total marks | $50 \times 100 = 5000$ |
Knowing how to calculate the total marks from the average marks and the number of students is a fundamental concept in statistics and quantitative problems. The total marks represent the sum of individual scores.
The final answer is the value calculated for the total marks.
